Abstract: The imbalance between fluid intake and sweating during sports activities can lead the individual to hypohydration, causing damage to health and physical performance. The aim of this study was to evaluate the hydration status of football players in the sub-15 category of a Serie A club in Brazil. Nine under-15 athletes (64.9 ± 8.6 kg, 171.3 ± 8.3 and BF= 9.3 ± 1.6%) were evaluated in three collective training sessions (T1, T2 and T3). The athletes' body mass was measured before and after training. Fluid intake and training time were recorded by the researchers. From this information, the sweating rate (SR), total fluid intake (TIL), dehydration (% weight loss) and fluids replacement rate (FRR) were calculated. The distance covered by the players during training was provided using the GPS Pro Soccer device. SR was 2.4 ± 0.6 L / h at T1 and complete at T2 (3.1 ± 1.3 L / h) compared to T3 (1.9 ± 0.6 L / h) (p = 0.039). The average TIL in the three training sessions was 1.79 ± 0.57L / h and the FRR ranged from 72.8 to 86.1%. There was no significant variation in the dehydration rate (T1 = 0.38 ± 0.48%, T2 = 0.9 ± 0.93% and T3 = 0.5 ± 0.39%). Extensive individual variation was observed in all hydration parameters. We conclude tha dehydration was low, but the extensive variation observed reinforces the recommendation of an individual approach for the adequacy of fluid replacement.
